Block Diagram

Figure 8.1 shows a block diagram of the EEPROM.

The built-in timer generates the write/erase sequence. The clock pulses for this timer are obtained
from an on-chip oscillator and are independent of the CPU clock. Changing the CPU clock rate
(external clock) does not affect the EEPROM write/erase timing.

The voltage pumping circuit generates the high voltages needed for writing and erasing. No
external high-voltage power supply is required.
